Fusion manufacturing setups

00:03

Throughout the next few videos,

00:05

we'll be discussing how to program the machining of this bracket using fusion 360.

00:09

Before we can begin creating any tool path operations, we must create a setup.

00:13

The setup will define our word coordinate system and location.

00:16

Our version of the nomen

00:17

stock dimensions and operation type.

00:20

Let's begin with the part on the right which we will define as our set up one

00:25

to create a setup, pick the setup command from the toolbar.

00:28

This opens the setup dialogue box and shows a preview

00:30

of the current origin W CS orientation and stock.

00:34

Firstly, we need to select our operation type.

00:37

The operations available are milling, turning or cutting.

00:40

I'm gonna select milling

00:44

now that I've told fusion what type of process I want to do?

00:46

I'll start out by defining my model geometry

00:51

when more than one body is present.

00:52

Fusion defaults to selecting nothing as the model geometry.

00:55

So I'll select my part to tell fusion which

00:58

bodies I want to include in my model geometry.

01:01

I can select bodies by clicking them directly or

01:04

I can select bodies from the feature tree.

01:06

Now that we have selected our model geometry.

01:08

You will notice that fusion has updated the

01:10

yellow stock preview to fit the model selection

01:15

note that you can cancel all of your selections at any time by clicking the X in

01:19

the model selection dialogue or re clicking the

01:21

highlighted body in the model or feature tree.

01:24

For model based tool paths,

01:26

only bodies identified as model geometry will

01:29

be considered during tool path calculations.

01:32

In addition to selecting model geometry,

01:35

we can also identify any fixture geometry.

01:37

The same way we selected model geometry

01:40

defining fixture geometry is not essential.

01:42

However,

01:43

it is useful as it allows fusion 360 to

01:45

identify potential collisions with fixtures during stock simulation.

01:50

Now that we have identified our model and fixture geometry,

01:53

we return to our W CS selection shown with what

01:56

we call a triad and what you might have called a

01:58

nomad and master cam fusion allows you to set the W

02:01

CS relative to the model no matter how it's oriented,

02:04

giving you flexibility regardless of who did the design work.

02:08

By default, we can see our orientation will be defined from the model orientation

02:13

by selecting the drop down.

02:14

We can see the options we have for selecting our W CS orientations.

02:18

We can select a combination of any of the two xy or Z axis

02:23

or select an existing coordinate system from our model. In

02:26

this case, I will select Z axis plane and X axis

02:30

to select my Z axis.

02:31

I can select any straight edge, cylindrical face or flat face on the model.

02:37

You can also select work geometry like planes or axis if desired.

02:42

If either axis is placed in the reverse of the intended direction,

02:46

we can reverse the axis direction.

02:48

By checking the flip axis check box,

02:52

you can also orient the axes using the triad by clicking the stem of the

02:56

arrow to define the direction and the tip of the arrow to flip its direction,

02:60

making it quick and easy to set the W CS orientation.

03:04

There are several options available for selecting their W CS position.

03:08

None of which require entering coordinate values.

03:10

Model origin will align the W CS to our model origin position

03:15

selected point,

03:16

lets us position our W CS at any point

03:18

on the model including center points of round features.

03:21

This option makes it easy to continue

03:23

machining based on a previously manufactured feature.

03:27

Stock box point allows us to place our W CS at a point on our stock box.

03:31

And model box point allows us to place our W CS

03:34

at a point on a bounding box that surrounds the model.

03:38

In this example,

03:39

I will use stock box point and select the center of the top face

03:43

for our stock so that we can easily probe the origin during setup.

03:47

It is important to note that if the models we use to define the W CS change,

03:51

our W CS will also change.

03:53

Keep this in mind when making late model or stock size changes.

03:58

Next, we will navigate to our stock tab. In

03:60

this tab, we can define our stock shape, location and dimensions.

04:04

Firstly, we will select our stock mode

04:06

fixed size box will create a box around our part with defined absolute dimensions.

04:11

Relative size box will create a box that is dimensioned relative

04:14

to our model size,

04:15

fixed size cylinder and relative size cylinder

04:18

afford the same functionality as their box counterparts

04:21

but will create a cylindrical profile,

04:23

fixed and relative size tube offer the same

04:26

options as fixed and relative size cylinder.

04:28

But allow us to specify an inner diameter.

04:32

With the from solid option. We can select any body in our design to use as a stock.

04:37

It is worth noting that these bodies can be solids or mesh bodies.

04:41

The from solid option is useful when our initial stock is a complex shape,

04:45

perhaps from a previous forging casting or additive

04:48

process to reduce the time spent cutting air

04:51

from solid is also great when we are creating a

04:54

setup for a side two of a previously machine part

04:58

for our current setup, I'm going to select the fixed size box option to create a box.

05:03

I'll set the width to 2.5 inches and leave the model position as center.

05:07

I'll set the depth to 3.5 inches and the height to 1.8 inches.

05:12

I'll change the Z model position offset from top

05:15

this will place my slock beneath the part,

05:18

giving us a good amount of material to hold on to in our vice.

05:21

I'll set the offset to 50 thou so we have some

05:24

material to face off on the top of our part.

05:27

The last tab in our setup dialogue is the post process tab.

05:31

Here we can specify a program number and comment.

05:33

This is also where we assign our W CS offset number.

05:36

This is the option that tells our post processor which machine offset to use.

05:41

Currently my W CS offset is set to zero which

05:44

will correspond to my machine's first W CS offset.

05:47

For example, G 54

05:49

it is important to note that both W CS offset number

05:52

zero and one are linked to our machines first offset.

05:56

If I set my W CS offset number to two,

05:59

my machine's next W CS offset will be selected for example G 55.

06:03

Then this continues sequentially for all W CS offsets available on my machine.

06:09

Now I can select, OK. And my setup will be generated

06:12

and we are ready to begin adding operations.

06:15

Note that each operation within the setup will inherit that setup to

06:19

CS and stock material.

06:21

The setup can now be found in the feature tree and

06:23

edited at any time by right clicking and selecting edit.

06:26

When we have multiple setups.

06:28

It is important to ensure that we have the correct setup activated.

06:33

Let's quickly take a look at creating our second setup,

06:36

which will be responsible for machining side two of our part,

06:40

I'll select new setup and you can see a new

06:42

setup called setup two is placed in the future tree.

06:47

As before I will select my model and fixture geometry.

06:50

I will also assign my W CS using the select Z and X axis.

06:55

Finally,

06:56

I will set my stock origin as the top

06:58

center of the stock using the stock box point option

07:03

for this setup.

07:04

I'd like our stock profile to represent the material left on our part.

07:07

After our first set up to do this,

07:10

I will navigate to the stock tab and select the from solid option.

07:13

In the case of this part,

07:15

I already have a mesh body which represents the stock left after my first setup.

07:19

So I can navigate to my model geometry and select the mesh body as my stock profile.

07:25

Now that I've generated my code,

07:26

you can see that our setup one program has called a G 54 W CS offset.

07:31

And on the right, our setup two has called a G 55 W CS offset.

07:37

Now that we have created setup two,

07:39

you will notice that the setup has automatically been activated in our future tree.

07:43

This is important as in creating tool paths,

07:45

they will automatically use the wcs and be placed under the active setup.

07:50

So it's important to make sure that you activate the setup,

07:52

you want to work in when creating tool paths,

07:55

I will activate setup one by selecting the button next to the setup name.

07:60

The last thing I want to mention in this video is W CS probing fusion 360 can

08:05

access the automatic probing cycles within your machine tool

08:08

control and generate automatic probing cycles for setups.

08:11

This is very useful when we have high quantities of the same part and we want fast,

08:16

accurate and repeatable setups.

08:18

It is important to note that while WCS probing is fully

08:21

integrated in the fusion and doesn't require an additional download,

08:24

a serial number,

08:25

it is only available when supported by your machine tool controller.

08:29

So be sure to check this before attempting to use this functionality

08:33

to create a W CS probing operation.

08:36

I will navigate to the probing tab and select a W CS pro function.

08:40

This will create a W CS probing operation in my feature tree

08:43

under my active setup and bring up a W CS probing dialogue.

08:49

Firstly, in the tool tab,

08:51

I will select a probe tool for my tool library.

08:53

Next, I will navigate to the geometry tab. In

08:56

this tab, I will set the probe mode to stock. This will tell fusion.

09:00

We want to probe our stock. As opposed to the model geometry

09:05

for my probe stock surface, I will select the top face of my stock.

09:09

You will notice that the probe type has default to an xy rectangular boss operation.

09:14

We could also change this to a Z level operation

09:16

which will probe the top face of our stock.

09:18

In Z.

09:20

The approach value specifies the distance away from the

09:24

feature that the probe will begin the measurement operation.

09:27

In this case, it's the clearance from the X and Y walls.

09:32

The over travel specifies the distance beyond the expected location

09:36

that the probe will move before returning an error.

09:38

If no contact was made,

09:41

I will navigate to the actions tab and select the override driving W CS option

09:46

in the W CS override box, I will specify WC S3.

09:50

This means our probing operation will be driven from our machines.

09:53

Third work offset G 56 for example,

09:57

but we'll set the new work offset values to our current active W CS offset.

10:02

In our case, G 54.

10:04

This means we are constantly driving our probing operation from the same

10:08

coordinates as opposed to overriding our originally probed work off set,

10:12

limiting the effects of creep.

10:15

I will select OK for my operation

10:17

and simulate my probing operation by right clicking on the W CS probe operation

10:21

and selecting simulate.
